Replaces []Format with a Group type.
A bit more type safe.
Breaking change for RegisterFormat, now takes a first argument that is a "single" format group.
Lots of naming cleanup.
This is also preparation for decode group argument which will enable doing intresting
probing, ex a format decoder could know it's decode as part of probe group (html could
be probed possibly), or have "arg probe" group for decoder who inspect args to know
if they should probe (-d /path/to/schema etc) to enable nice CLI-ergonomics.
Preparation to make decoder use less memory and API more type safe.
Now each scalar type has it's own struct type so it can store different
things and enables to have a scalar interface.
Also own types will enable experimenting with decode DLS designs like
using chained methods that are type aware.
Refactor mp4 decoder to be simpler and have fallback for unknown box type
Cleanup some old ilst hacks
Add generic string reader to decode API that takes an encoding parameters
Rework time helpers to use new functions
Fix panic in tar decoder where sym value might be missing
Still not very happy about the API but it's getting better.
Decode API design is that Try* returns error non-Try panics.
Also rename Must* as they should panic and introduce some new Try* functions
that were missing.
Each trun has it's own data offset, before the last offset was wrongly used
for all truns. Could also cause sample ranges to be beyond EOF.
tenc: Decode default constant iv
Fixes#292
PSSH decoding probably got broken in some refactoring. system id is 16 bytes,
also scalar mapper should use cloned reader to not affect reader which in the case
broke reading system id bytes.
Add test with playread and widevine pssh boxes
Related to #282
Rename s/interface{}/any/g
Preparation for using generics in decode API and native jq funcations etc
Remove some unused linter ignores as linter has been fixed
Will produce one field per sample which is a bit too much.
Maybe in some future fq can have smart array types that could handle this better.
Also add data_format per track to make it easier to understand things.
Fragmened mp4s can have no tkhd box or tkhd box with a track_id that does not match
any tfhd box track_id. Make is possible to see samples for these fragmented tracks
ny adding tracks for unseen track_ids.
Also add id field for tracks.
interp: Refactor format help and also include options
interp: Add -o name=@path to load file content as value (not documented yet, might change)
interp,decode: Expose decode out value as _out (might change)
interp: Refactor foramts.jq into format_{decode,func,include}.jq
interp: Refactor torepr into _format_func for generic format function overloading
interp: Refactor -o options parsing to be more generic and collect unknowns options to be used as format options
decode of decode alises
func for format overloaded functions
include for format specific jq functions (also _help, torepr etc)
